Milan Synod, is actually much closer to Eastern Practices than most western rite congregations.I have seen some western rite parishes using levened bread that has been pressed flatwith seal on it being, likewise I have seen small loaves similar to a slavic style prophora being used in communion with small cut pieces being given during the commmunion. Most , but not all, western rite congegrations seperate the bread and wine, some cradling the bread (Body) reverently in their hand than then taking it to their mouth (most like Orthdoox Clergy do when they commune) and others have it placed on the tongue directly by the priest.
Exactly - in ROCOR WRITE, we normally use small leavened loaves after the ancient Western manner - strangely enough similar to what some Anglicans have used over the past few centuries. They follow the early canons of the Western local councils of Braganza and Braga - they are small, white, whole, round, wheaten, and leavened. Normally they are marked with a cross, and at the preparation are cut into small cubes (three cuts with the formula 'Jesus Christ, the Alpha and Omega, the First and the Last'). The small portions are arranged on the paten in the form of a wheeled cross (which one can see in the Stowe Missal, in fact, so it is quite old.)
We also have some variation on how people receive, like the AWRV. Some kneel, some stand - normally we receive at the chancel arch/rood screen, with the white houselling cloth held beneath our chins. A throne is made with our hands for receiving the body, and we drink from the chalice, just as the rubrics for the liturgy of St. James share with our rite - infirm can be intincted, IIRC. (Though I haven't seen it done.)
